GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 495,670, dated April 18, 1893.

Application filed January 12, 1893. Serial No. 458,147. `(No model.)

ment,be changed from a straight line to a zigzag line or vice versa; and it has for its object the simplified and improved construction of r the machine.

The novelty of my invention will be hereinafter set forth and specifically pointed out in the claims.

In the accompanying drawings: Figure l, is

zo a side elevation of a grain drill embodying my invention. Fig. 2, is a plan View of one cornerof the main frame. Fig. 3, is a perspective of the corner block and bearing for the rock-bars. Fig. 4., is a sectional end elevation of the rock-bars and connected parts. Fig. 5, is an enlarged elevation of one of the clips for the drag-bars.

The same letters of reference are used to indicate identical parts in all the figures.

The drill may be of the usual or any suitable construction, eXcept in the particulars to be pointed out, and in describing it generally it is only necessary to say that A are the supporting wheels, B the hopper, C the main frame, D the spouts from the seed mechanism, E the hoes, F the drag-bars for the hoes, and G the tongue or pole. y

The main frame is constructed of three straight pieces of L shaped angle iron or steel, two of which form the parallel side bars and the third the front cross bar. At the front corners these bars are bolted to a subjacent casting H, Fig. 3, with a rounded corner and raised boss a against which the top ends of the bars O of the main frame abut. The block or casting H is substantially L shaped vin section so as to t snugly in the angle of the bars C, as shown by the dotted line in Fig. 3, and the rounded corner projects out 5o to form shoulders b for the side ends of the bars C to abut against, thus forming a very simple and secure coupling forthe corners of the main frame. In addition to their office as a coupling for the main frame the pendent side walls of the pieces H are provided each with two circular apertures c with inwardly extending bosses in which apertures are journaled studs upon the intermeshing segment racks I, Fig. 4, to which the rockbars J are bolted. These rock-bars, as seen 6o in Fig. 4, are constructed of angle metal and the forward ends ofthe drag-bars F are secured to them by the combined staple and clip shown in Fig. 5 where the stapleol passes through the fiat side of the rock-bar with one end riveted or upset, as seen at e and with the other end threaded to receive a clamping nutf. To stay and stiffen the staple, it is passed through a perforated clip g which has a leg h resting upon the rock bar and with 7o two fingers i overlapping and embracing the edge of the rock-bar, as shown. The projecting bow of the staple passes'through a perforation in the drag-bar. In this way I obtain great strength with a comparatively light and 7 5 a very cheap construction. One of the segment racks I has a proj ectin g arm j to which is pivoted the forward end of a rod la whose rear end is pivoted to the usual or any suitablelever K for simultenaously rocking the 8o bars J to straighten or zig-zag the hoes.

Having thus fully described my invention,

I claiml. In a grain drill, the combination with the main frame, composed of three pieces of angle metal, of the corner blocks for coupling the same bolted thereunder and having the bosses a and rounded corners with shoulders b, substantially as described.

Y 2. In a grain drill, the combination of the 9o main frame composed of three pieces of angle metal, the corner blocks bolted thereto for uniting the same, the hoes, the drag-bars and the rock-bars journaled in the corner blocks, substantially as described.

3. In a grain drill, the combination of the. intermeshing segments I, the rock-bars of angie metal bolted thereto, the hoes and dragbars, and the combined clip and staple for uniting the dragand rock-bars, substantially roo as described.
